Currently the default action is emergency_shell when failure happened
during system boot. In kdump, this default may not be expected. E.g,
if dump target is not rootfs, it does not matter if mount root failed.
Adding an action which allow dracut always go ahead though failure
happens is needed by kdump.
So here add a function action_on_fail() and cmdline parameter
action_on_fail=<shell | continue>. Use action_to_fail() to replace
emergency_shell which was called after failure. By $(getarg action_on_fail=),
decide to drop into shell, or to leave away the failure and go ahead.

Currently dracut only support 1 bond, namyly bond0 by default. However multiple
bonds configuration may be needed. For example in kdump, in 1st kernel, more
than one bonds may be configured, and bondX other than bond0 is used as output
interface to remote host which will store dump core. This patch can solve this
problem, to write real bond information to initramfs, 2nd kdump kernel will
use it to create the relevant bondX interface.

The following change makes the check for the nbd port or named export
more robust.
I wasn't sure whether to include sed in the dracut_install() of
module-setup.sh since net already does that (and nbd depends on that).
To use vlan for net boot, you need to specify vlan and ip kernel options
for the boot interface. For example,
vlan=eth1.1:eth1 bootdev=eth1.1
ip=1.2.3.4:1.2.3.4::255.255.255.0:my-hostname:eth1:none
To use bridge for net boot, you need to specify bridge and ip kernel
option for the boot interface. For example
bridge=br1:eth1 bootdev=br1
ip=1.2.3.4:1.2.3.4::255.255.255.0:my-hostname:eth1:none
In my environment, I needs to boot machines from network within
a vlan or on a bridged network. I found curent dracut release
if-up.sh script in 40network module bypass ip setting for both
bridge and vlan interface.
When dracut-lib.sh is sourced it checks the command line (when not using systemd)
as part of the check_quiet() call.
Therefore mount /proc earlier in init.
Avoids the error:
init: 77: /lib/dracut-lib.sh: /proc/cmdline: No such file or directory
Just like btrfs, xfs now requires CRC module that cannot be resolved via
normal module resolving.

No automatic assembly is done anymore by default. You will have to
specify exactly what devices to assemble
("rd.md.uuid=" "rd.luks.uuid" ...)

For big servers with thousands of disks we don't want to assemble
everything by default (error prone, slow).
"inst busybox" no longer seems to work when busybox is at
/sbin/busybox. Reproduced on Fedora 18 (dracut-023-39.git20120910).

ismounted handles both find-by-dev and find-by-mnt, but there's two issues:
1. for find-by-dev, it use readlink to get the canonical dev name, but
lvm is different with other devices, the canonical name for lvm devices
are symlinks like /dev/mapper/vg-lv00
2. for nfs mounting, just use [ -b $dev ] is not enough, it need being handled
seperately.
Per Karel Zak's suggestion, findmnt util is suitable for this purpose, it
handles these cases well, so just use findmnt instead of implement all the

When emergency_shell() happens, it does 'setsid --help' to figure out if

This output shows up in the logs (and on-screen if you're using

Currently anaconda provides rd.md=0 on kernel's command line as a boot
time optimization if root is not on md device. But this leads to kdump
failure. We copy the command line from first kernel and if dump target
is on md device, it fails as we never try to assemble md devices as
rd.md=0.
We have already set rd.md.uuid though in /etc/cmdlind.d/ dir providing
dracut the info about what md devices to assemble. So this patch overrides
rd.md settings if rd.md.uuid is provided.
This is a stop gap measure to get kdump working on software raid
devices. Harald seems to have bigger cleanup plans for rd.md. Once
that happens, this patch will not be needed and things should
automatically be fixed.

Anaconda used arguments of the form:

dracut allows passing --mount option which mounts the specified devices.
But it does not wait for these devices to show up and mounting will fail
if devices do not show up by the time "mount" was called.
I am writing some patches to support kdump on iscsi target and I noticed
that one of the initqueue script was not called as we found the root
device and broke out of main loop.
There are two possible enancements to this patch.
- Introduce a time limited wait (rd.timeout something along the lines of
rd.retry). That will allow kdump to try to dump to a backup target if
primary targets fails to come up.
- Wait for UUID= and LABEL= to show up too. Right now kdump converts
UUID= and LABEL= to respective devices and passes /dev/* to dracut
--mount option. So I am not introducing the wait for UUID= or LABEL=
in this patch.

you have two configurations for eth0.
If you're using a static network config, you'll want to keep your
nameservers around when NM starts. Write DNS1 (and DNS2, DNS3, etc..)
into the ifcfg file.
Thanks to Mark Hamzy <hamzy@us.ibm.com>
and Will Woods <wwoods@redhat.com> for the patch.
Basically, s390 is the only place I've ever seen TERM=dumb, and it's too
dumb to handle '\r', so --progress-bar produces waaaaay too much output.
The normal progress meter only prints something once per second, so
that's reasonable on terminals where '\r' doesn't work.

Every time url-lib gets imported we end up making the list of handlers
longer with redundant entries. That's silly - we shouldn't add items
that already exist.
Note that this means you'll have to manipulate the handler list yourself
if you want to change the position/priority of existing handlers.
Sometimes some hook script will need to be before the cleanup hook scripts
For example dhclient killing, nfs cleanup, etc. must not happen before kdump
because it will use their fuctionalities.
So here introduce a new hook pre-pivot-cleanup, all cleanup scripts will go there.
that means pre-pivot hook is splited to two hooks pre-pivot and pre-pivot-cleanup

Qemu/KVM provides virtfs, a paravirtualised filesystem that is
implemented by running the Plan 9 folder sharing protocol over
virtio.
Make booting with root=virtfs:foobar use the virtfs filesystem
with mount tag 'foobar' as root filesystem, to allow booting
virtual machines off virtfs.
Note that this only handles 9p over virtio (i.e. virtfs), and
doesn't attempt to handle mounting 9p filesystems over TCP/IP,
for example.

Currently dracut uses lvm.conf as found in the system and modifies only
global/locking_type setting. As there's a new feature introduced - the lvmetad
daemon, dracut should disable its use as well by setting "global/use_lvmetad=0"
(patch attached).
Otherwise, there's a warning message issued:
dracut: WARNING: Failed to connect to lvmetad: No such file or directory.
Falling back to internal scanning.

Another solution could be searching in directories found at
/etc/ld.so.conf.d/*.conf or adding a new parameter. Here is a patch
which adds a new --libdirs parameter, and also a new inst_libdir_file
function which will try to expand metacharacters on each lib
directory:
inst_libdir_file "libdevmapper-event-lvm*.so"
Mounting, unmounting and then mounting a disk partition takes some
time.
On embedded systems such as OLPC XO where we disable fsck and fstab
reading, the root options are not going to change throughout the
mount_root() function, so remounting is time consuming and without
change.
Detect and optimize for this case so that the filesystem is only
mounted once.
According to its comment in dracut-lib.sh:
splitsep ":" "one:all:the:rest" one two
should set two="all:the:rest". But there's no check to see if the
current field is the last field, so it just gets "all".
For NetworkManager to properly take over a NFS-root system, we need to
have the interface name(s) in /tmp/net.ifaces and save the dhclient
lease. This lets the ifcfg module do its magic.
save_netinfo should properly write out /tmp/net.ifaces when needed, and
copies the dhclient files into place.
This makes sure the network is active and ready to use during the
initqueue/online hook.
It also makes it so you can run setup_net repeatedly without causing
error messages.
also fixup the logic what and when to mount.
first initramfs/etc/fstab is mounted
$NEWROOT/etc/fstab.sys takes precendence over initramfs/etc/fstab.sys
"export -n" is a bash extension, not part of POSIX, and is hence
incompatible with the busybox shell.
This was breaking boot when the busybox module was used.
Reimplement the scope change in a few lines of standard shell code.
wait_for_loginit does set +x (to turn off debugging temporarily), but
sometimes it would return before turning it back on. Move the set +x
line to fix that, then use 'setdebug' to make sure we don't turn it back
on unless it was needed.
